Mar 14 13:22:59 squeeze postfix/local[17547]: A93DE49A55:
to=<etutest at squeeze.test.ecp.fr>, orig_to=<etudiant.test at test.ecp.fr>,
relay=local, delay=0.07, delays=0.04/0.01/0/0.02, dsn=2.0.0, status=sent
(delivered to maildir)

Your postfix rewites the recipient domain to "squeeze.test.ecp.fr",
which is no virtual domain (it is $myhostname). You enabled dovecot only
for virtual domains. You probably don't want to rewrite the domain.

Note that this is a postfix config issue, not a dovecot issue.
